    I don't seem to get these old one removed. Oh yes, I can do it through apt autoremove,
    but I kinda thought this would work.

    What am I doing wrong?


    I don't recall the update manager working on "time", but rather a count
    of how many kernels to retain (e.g. "keep 2 old kernels"). That being
    said, 'autoremove' should only be removing packages that were installed
    as dependencies of something that has since been removed. The kernel
    images "shouldn't" fit this definition (although, maybe there's a
    metapackage that's driving it).


    Have you happened to jump kernel versions (e.g. default LTS to HWE, or similar)?

    Nope. I currently have

    Nov 20 11:15 /boot/initrd.img-6.8.0-87-generic
    Nov 20 11:15 /boot/initrd.img-6.8.0-88-generic

    Maybe it's 1 active and 2 old, as you said. I'll see what happens on the next update.
